摘要： A dedicated bus between a central processing unit and a peripheral unit, such as a graphics controller driving a video display, provides enhanced capability in an environment in which signal processing occurs within the central processing unit. The dedicated bus relieves other data buses, such as the PCI bus, of the need to communicate large amounts of data, such as decompressed video data. The resulting system supports high bandwidth transmissions of decompressed video data, enabling high resolution 24 bit full motion video and multiple data stream video.

摘要： A data bus for connecting information processing devices is configurable into a plurality of subbusses in order to fully utilize the data bus capacity. The size and data transfer direction of each subbus, as well as the data transfer speed of each subbus, is independent of the other subbusses. Also, the data bus can be reconfigured to meet changing system requirements. A data bus controller is thus provided to accomplish this data bus reconfiguration. The reconfiguration may be accomplished in accordance with one of a plurality of information flow templates which may be stored in a memory. A method of configuring a data bus is also provided wherein information transfer needs of a system are identified and the data bus is configured according to the identified information transfer means. The reconfiguration in accordance with the information transfer needs may be accomplished in accordance with one or more information flow templates which may be stored in a memory. The system may operate in accordance with a self arbitration scheme such that reconfiguration of the system is based on operational experience, such as utilization rates or excess capacity associated with each of the subbusses.

摘要： A method of allocating bandwidth among a plurality of devices communicatively connected through a data bus provides for determining a data need of at least one of the plurality of devices, allocating portions of the data bus to the devices in response to the data need, and transmitting data between the devices on the allocated portions of the data bus. The portions of the data bus can be subbusses, each comprising at least one bit line. The data need can be based on a measure of fullness of a buffer corresponding to the at least one device. The data need can be provided as feedback from the buffer to a data bus controller which allocates the portions of the data bus. The method can use rules for assigning the subbusses which are stored in a memory. A processor can change the rules to accommodate changing conditions in the data bus. Also provided is a data communication system comprising a dynamically reconfigurable data bus, a data bus controller connected to the dynamically reconfigurable data bus for configuring subbusses of the data bus, a plurality of receiving devices connected to the data bus, and a feedback connection from at least one of the receiving devices to the data bus controller, wherein the data bus controller configures the subbusses in accordance with feedback received over the feedback connection. A memory can be connected to the data bus controller for storing rules for use by the data bus controller in configuring the subbusses. A processor can change the rules to accommodate changing conditions in the data bus.

摘要： A dockable computer system is capable of performing symmetrical multi-processing operations. More particularly, the dockable computer system includes a portable computer and a host station (docking station), each including a resident CPU. The dockable computer system is capable of operating in a docked state in which the portable computer is physically joined with the host station and an undocked state in which the portable computer is physically separate from the host station. In the docked state, the dockable computer system is capable of performing demanding computational tasks such as video conferencing as one of the CPUs in either the portable computer or host station is dedicated to the video conferencing operation. The dockable computer system preferably includes a communication channel for transmitting multi-processing support signals between the portable computer and the host station. Multi-processing support signals include synchronization signals, cache coherency signals, and interrupt distribution signals such as the LOCK signal, PLOCK signal, FLUSH signal, EADS signal, INTR signal or INTACK signal. The communication channel may be a dedicated bus or may be provided through a docking bridge between the portable computer and host station. The dockable computer system advantageously optimizes CPU resources when the dockable computer system is in a docked state.

摘要： An interrupt polling unit included within a bus interface unit of a microprocessor is provided. The interrupt polling unit causes a periodic interrupt acknowledge bus transaction to occur. If an interrupt controller receiving the interrupt acknowledge bus transaction returns an interrupt vector indicative of an interrupt service routine, then the microprocessor executes the interrupt service routine. The number of interrupt acknowledge bus transactions associated with the interrupt is reduced from two to one, and the microprocessor effectively prefetches the interrupt service routine before the interrupt is actually signaled. In one embodiment, the interrupt polling unit causes an interrupt acknowledge bus transaction to occur at the expiration of a programmable time interval. Another embodiment of the interrupt polling unit causes an interrupt acknowledge bus transaction subsequent to the occurrence of a bus transaction programmed by the user.
